Description
Valve shim clearance directly impacts your engine’s efficiency and longevity—improper spacing leads to valve float, compression loss, and potential catastrophic failure. PROX Valve Shims are precision-machined to exact tolerances and heat-treated for superior hardness, ensuring consistent performance across extended racing seasons without unwanted wear or degradation. Stock shims often fail to maintain their dimensions under high-lift cam profiles and aggressive valve train dynamics; these shims hold their specs.
